Infrared radiation spin photocurrents have been observed in GaN quantum well structures. Observed currents change sign upon reversing of radiation helicity demonstrating an existence of Rashba/Dresselhaus spin splitting of the conduction band in this new type of materials. Approvement of spin degeneracy removal in GaN structures allows to consider this material as a candidate for semiconductor spintronic.
